If you already have a speaker stand with spikes and your floor is made of wood, then you should consider putting some form of isolation platform between the speaker and the stand, to prevent the cabinet vibrations reaching the stand and, through it, the floor. Avoid flimsy stands that move or rock when you touch them. If the final assembly doesn’t feel completely solid, avoid it.
You can make a speaker move less in many different ways, and one of those is by adding more mass to the speaker and the stand; making it harder for the speaker to move. That’s why you’ll find a sand compartment in most stands.
All that unwanted movement can colour and distort the sound. We do our best to prevent vibrations by adding bracing to the cabinet, but that doesn’t really help with the movement.
Thus, the sand provides dampening, but it also prevents the stand from ringing when it’s excited by the right frequencies – another handy little add-on.
